AUTOMOBILE-JACK.

Application filed January 8, 1017.

To all whom it may romwlrn Be it known that we. li'larrico Dr. (insane and Jenni-ii Dumas iinuu, subieels of the King of Italy residing at (fliiton. in the county of Passaie and State of liew Jersey, have invented certain new and useful ln1- provements in Alll()lil()bllb-rl:llfkS, of which the following is a speeifiration.

This invention relates to automobile jacks. and more particularly to a jack adapted to be mounted on an automobile so as to at all times be in position for use.

One of the main objects of the invention is to provide an automobile having a plural ity of jacks secured thereto so mounted that, by reversing the drive of the automobile,

' one or all of the wheels of. the vehicle may be jacked up or raised from the ground surface. A further object is to provide a jack ot'simpl construc ion and operatitm 'eapze ble of being mounted on an automobile frame and means in! noru'ially holding the jask in inoperative position. A. still further object is to provide simple and ellicient means for holding the jack in inoperative position whieh may be easily operated so as to release the jack. Further objects will ap war from the detailed deseriptimi.

Fig. isa detail view in sertion on an en larged scale of the bolt and easing.

Below and parallel with each side bar 1 of the frame of the automobile A is mounted a longitinlinally extending bar 2. The front end of this bar is riveted to a supporting plate which is secured to the front axle t and spring 5 of the autonmbile by means of crossed U-elips 6 passed about the axle and spring with the ends of their arms inserted through the plate 3 and secured through the same by nuts, in the usual man- Speelflcntion of Letters Patent.

ner. [it its approximate center the plate ii is provided with two spared downwardly extending lugs 'i. ."i jack arm h is provided at its upper end with oll' set ears .l which are pivotally serured to the lugs T by the pivot bolt l(). A hearing wheel ll is rotai'ably mounted in the free end of this arm.

The side walls oi arm t at the lower end thereof. are out to form a triangular point 12 whioh extends noun-what beyond the pe riphei'y of wheel it and beiow the axis olf rotation of the wheel.

A pair of spaced lugs 13 are provided at the forward end ot plate 53 and extend downwardly therefrom. A sleeve l-l has its forward end pivolally secured between these lugs, as at 15. This sleeve is bored out to slidably n'weive a brave rod 16 the end of which is pivolidly slllllktl between the side walls of the jack arm as at U. lVhen the jael: awn b is dropped. the points 122 of arm R will his: engage the snrl'are upon which the automobile is traveling. It the direction of travel of the automobile be reversed, so that is is driven luu'lcward, the points 12 will bite into the ground surface so as to prevent rearward nmvement ol the jack arm. As the automobile moves rearward the iael; arm 8 will be swung downward and forward about the pivot pin '10 so as to raise the automobile wheel adiacent which the jut-l; is mounted. When the axis f rotation f the wheel ll is passed l'orward beyond the axis ol pivot pin it). wheel ll will be brought into emyulelneut with the ground sin-fare. With the inch in this position the weight of lhe aulrunobile will tend to force the jar-h forward. this 't'orward movement of the look being positively limited by rod H3 and sleeve ll. the bore in sleeve Ill beingof such length as to permit movement of the jack arm 8 int o an approximately verlieal position. as in Fig. 3 oil the drawings. In this position the sleeve l t and brace rod 16 constitute an inclined brace which hold the jack in operative position, all tendency of the jarrl'. to move rearward being eliminated due to the. fact that the pivot pin 10 is behind the axis'ot' roller or wheel 11. W hen it is desired to lower the' machine. it is only necessary to drive the automobile forward. This \Vl-ll force the wheel 11 rearward of the machine, due to the load upon it and its frictional cngragement with the surface of the ground. suf

ficicntly to bring the point 12 of the jack erative position so as to lower the automobile Wheel, as will be evident. In this position the jack 'is free to be raised upward and rearward into approximate parallelism with, and closely adjacent, the underface of plate 3, in which position it is normally secured by a suitable securing means.

. Adjacent the inner end of plate 3 is -mounted a casing or housing 18. A bolt 19 is slidably mounted through this housing and is normally held in forward or extended position by a coil expansion spring 20 mounted about the bolt within the housing andconfined between the inner end of the housing and a pin 21 passed through the bolt. The forward end of bolt 19 is beveled upwardly, as at 19 and projects into the casing 18. This bolt is adapted to engage into an eye 22 secured to the jack arm 8 at the back, and near the lower end, of the same. \Vhen the jack is raised into inoperative position, bolt 19 engages into eye 22 thus securing the jack in the position indicated by broken lines in Fig. 2 of the drawings. To release the jack a cable 23 is secured to the inner end of bolt 19. This cable is passed about a guide pulley 24: mounted on the inner face of bar 2, and is secured to one end of an arm or lever 25 secured on a stubwall of easing 18,-and the partition 19 intermediate the ends of the casing. The cas ing 18 is provided with an opening 18 in vertical alinement with the bolt 19 to-accommoda-te the eye 22 of the jack. By this construction the casing 18 entirely incloses the lock bolt so as to protect the same, all danger of the user or his clothing being torn or injured by the bolt being thus eliminated.

eeann In practice we provide a plate 3 and a jack carried thereby adjacent each wheel of the automobile, and provide means similar to that described for holding each jack in inoperative position. and a rockable shaft arm for releasing any jack desired. As will be clear from Figs. 1 and 3 of the drawings, by rocking either one of the shafts 26 or 26 in either direction desired. any one of the four jacks may be released so as to be moved into operative position or, if desired, all four of the jacks may be released so as to jack or raise the whole machine.

As will be noted more clearly from Figs. 1 and 4 of the drawings, the bar 2 is formed of two sections or members 29 and 30. These two sections overlap at their inner ends and are each provided with a central longitudinally extending slot 31 adjacent its inner end. Two set screws are passed through the slots 31, and a binding nut 33 is threaded on the inner end of each screw. By this means the two sections of the bar may be quickly and easily secured in adjustment so as to vary the effective length of the bar to accomodate automobile frames ofdiflerent lengths.

There may be slight changes made in the construction and arrangement of the difi'erent parts of our invention Without departing from the field and scope of the same, and we intend to include all such changes, as fall within the scope of the appended claims, in this application in which a preferred form only of our invention is disclosed.
